Were you watching something from an external source (HDMI or USB-C) by chance?
It could be that your charger was already defective, and that you didn’t realize it wasn’t charging the PPX properly or at all. Then because you were using an external source, the battery warning did not show, and the battery actually ran out. Now when you connect the deceased charger to the PPX nothing happens, and without power you can’t charge it.
This theory doesn’t explain the circuit breaker tripping, and especially not the whole house, but it could explain why you have an empty battery and no power being supplied to your PPX.
If you have a similarly specced charger or powerbank you can test whether it will charge the PPX, albeit slowly.
Otherwise we could arrange for me to meet you to test my working charger and troubleshoot where the issue lies. I live in Utrecht so either you could come to my place or I can come to yours.
PM me if you think you want to try this approach.
